A4970 Dual Full-Bridge PWM Motor Driver

TheA4970 motor driver drives both windings of a bipolar stepper motor or bidirectionally controls two DC motors. Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 750 mA. For PWM current control, the maximum output current .
